Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.
What Is CISCO-WAN-PERSISTENT-XGCP-EVENTS-MIB?
CISCO-WAN-PERSISTENT-XGCP-EVENTS-MIB manages persistent XGCP (a generic term covering MGCP/SGCP-style gateway control protocols) event notification configuration for Call Agent (CA) to media gateway signaling on Cisco WAN platforms. It exposes a simple table of named events (persistentXgcpEventName) that should persist across gateway resets, controlled via row status. Its monitoring role is configuration-state verification for VoIP/media-gateway control signaling: confirming which XGCP events (e.g., off-hook, on-hook, or fax-tone detection style events) remain registered as persistent so the Call Agent continues to receive them after a gateway reload, with an unexpected missing or inactive entry signaling a lost event registration that could cause call-control signaling gaps. It is a companion MIB to the broader Cisco WAN media-gateway control MIB set (including CISCO-WAN-SRCP-MIB and CISCO-WAN-MG-MIB) built on MGCP/SGCP-family concepts rather than a specific IETF standard. Administrators typically start with a CISCO-WAN-PERSISTENT-XGCP-EVENTS-MIB download from Cisco's MIB repository so the module can be compiled into their SNMP tooling before it is deployed in Cisco MGX-based media gateway/Call Agent voice networks.
IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-WAN-PERSISTENT-XGCP-EVENTS-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- Cisco WAN media gateways (MGX-based Call Agent/gateway platforms)
Monitoring Examples
An operator would check persistentXgcpEventsTable, indexed by persistentXgcpEventNum, to confirm persistentXgcpEventName entries for critical signaling events retain a persistentXgcpEventRowStatus of active after a gateway reboot. If an expected event's row status reverts to notInService, the Call Agent may stop receiving that event notification from the media gateway, causing a call-control signaling failure.
What Can Be Monitored
- persistent event registrations
- event names configured
- row status/activation of persistent events
